Question 1

Describe the superior and inferior tibiofibular joints,including classification and their composite function.

Accepted Answer

The superior and inferior tibiofibular joints perform the function of maintaining the mortise while permitting some motion between the malleoli,which is necessary to permit full range of ankle motion.The superior tibiofibular joint is a plane synovial joint between the head of the fibula and the posterolateral tibial condyle.It has a separate joint capsule,which generally has no connection with the knee joint.The inferior tibiofibular joint is a syndesmosis,a fibrous union of the distal tibia and fibula.The two joints maintain the apposition of the tibia and fibula,assuring an appropriate (but slightly changing)grip of the mortise on the talus and,therefore,stability of the ankle joint.
